characters (m0, ml and m2) are used to specify the width of the character and the space to be allowed on either side of it. The left space (in dot column) is specified by m0 and the right space is specified by m2. The second byte (ml)specifies the number of columns of dots that will be printed by the character. By vary- ing the width of the character itself and the spaces around it, you can actually create proportional width characters.
You’ll probably recognize dl d2 ... dx from the top of our layout grid. That’s right, each column is described by three bytes. Now we’ve got everything we need to download one character to the printer. The complete command for our car character with the Standard mode is shown below:
Now let’s send the information to the printer. The following
program will send the character definitions for all two characters to the printer. Before you enter the program, turn off the printer and set the DIP switch
After you set the DIP switch correctly, enter the program and run it.
